MECHANISM FOR TRANSMITTING ROTARY MOTION.

Specification of Letters Patent.

Patented Jan. 25, 1910.

To all whom it may concern:

Be it known that I, 'lnnormnns BnowN, a citizen of t.he United States. residing at \Vorcester, in the county of \Vorcester and Gonnmmwealth of Massachusetts, have invented a new and useful Improvement. in Mechanism for 'llransmitting Rotary Motion, of which the following is a specification, accompanied by drawings forming a part of the same, in which-- Figure 1 is a side view of the rear portion of a manure spreader embodying my invention. with one rear wheel removed. Fig. 2 is a view partly in section on an enlarged scale, of the gear connection between the rear wheel and the sprocket wheel. Fig. .3 is a view on an enlarged scale, of the toothed revolving shellshowing the arrangement of planetary gearing to drive the sprocket wheel. Fig. et is a sectional view'takcn on line 1-4, Fig. 3. and Fig. 5 is a side view. on the same scale as Fig. 1. of the toothed stop wheel by means of which the revolving shell is held, and the driving power brought into operative engagement with the sprocket wheel.

Similar reference letters and figures refer to sii'nilar parts in the different views.

My invention relates to improved mechanism for transmitting rotary motion, shown as applied to a manure spreader, and arranged to rotate the'beatcr from one of the rear supporting wheels, and it includes means mounted on the rear axle for the transmission of power from said rear sup porting wheel to a stprockct wheel connected with the l eater sha t, and so arranged that the sprocket wheel may be disconnected at will from the rear wheel: and it consists in the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings 1 denotes the body of the manure spreader provided with an endless bottom 2 and a heater 3. The shaft 41 of the beater is provided with a sproclt'et wheel 5 which is connected by a chain (3 with a sprocket wheel 7 attached to a sleeve 8 mounted on the rear axle f), in the well known manner. l urning on the axle 9 is a shell 10 having a hub provided with recesses 11, 11, in which are mounted pawls 12, 12, arranged to engage internal ratchet teeth 13 on the hub :10 of spreader is moved forward. but stands still when the spreader is moved backward.

The pawl and ratchet connection between the hub a: of the rear wheel and the driving mechanism of the heater is in common use and forms no part of my present invention. Inside the shell 10 are two plates 14, 15. fastened together at their points of contact by bolts 16, forming a framework Torintermediate pinions 17, which are mounted between the plates L1. 15, and are arranged to engage an internal gear 18 on the shell 10. The intermediate pmions 17 also engage a pinion 19 mounted on the sleeve 8 on the axle 9, forming the driving arrangement known as planetary gearing. The shell 10 is closed to dust by an annular cover 20. The plate 15 is provided with an angular, in this instance hexagonal, hub 21 on which is mounted a toothed stop wheel 22, a dog 23 operated by the lever 24; and link connected with a hand lever. not shown, at the wagon seat, is used to engage the teeth 26 of the stop wheel 2;, thereby holding the stop wheel and the plates. 14:, 15, from rotation. The sprocket wheel 7 is mounted on the sleeve 8 and therefore will be rotated by the revolution of the gear 1!), thereby rotating the beater through the chain (3 and sprocket wheel 5.

In operation the shell 10 is rotated from the forward movement of the rear hub a by the pawls 12, 12, and, if the plates 14. 15, are not held from rotation the shell 10 carries the intermediate pinions 17 around the pinion 19 without rotating it. When it ,is desired to rotate the beater the dog is dropped to engage a tooth of the stop wheel '22, thereby preventing the rotation of the plates 14 and 15. Further revolution of the shell 10 will rotate the pinions 1.7 and through them the pinion 19 and sprocket wheel 7, thereby acconmlishing the' rotation of the beater as has been described. I am thus enabled to connect or disconnect at will the sprocket wheel 7 on the rear axle with the hub :c of the rear supporting wheel of the manure spreader, thereby controlling the rotation of the beater. This permits a compact arrangement of gearing about therear axle which can be completely cased up to prote ct'from dirt. It "also allows a direct drive from the large sprocket wheel rotating concentrically with the main axle to the shaft .of the beater without intermediate .gearing, and also provides means for disconnecting thebeater at will, by releasing the toothed wheel 22, which is accomplished by simply raising the dog '23, thereby obviating the use of a sliding clutch connection on the rear axle. I furthercause the beaterto rotatein the opposite direction from the rear supporting wheel witholit the employment of exposed pinions. The shell or case 10, when the annular cover 2-0 has been applied, completely incloses the planetarygears and by inserting a gasket un der\ the cover or otherwise providing against leakage, the shell may be supplied. with oil and the gearing protected from dirt.

I- claim, I
